Chapter 1: Connecting and Using the 68K

Monitor

Overview

Connect Defined An application interface provides an input to and output from the 68K Monitor.
This allows the 68K Monitor to ‘connect’ to any application or subsystem, and to
any type of hardware (capable of stream or block transfers).
As examples:
 WESMAINT or the Login Process can connect the 68K Monitor to a serial port.
 WESMAINT and the TELNET application can connect it to the TELNET
session.
The 68K Monitor can also be ‘connected’ to a file system to receive (read)
commands from a file and send (write) responses to another file.

One 68K While any application running in the system can activate the 68K Monitor, only one
Monitor At-A- instance of the monitor can be active at any one time.
Time
If a second application attempts to start the 68K Monitor, it will refuse the second
application’s request.

68K Monitor The prompt produced by the 68K Monitor depends on the hardware platform and
Prompts the mode the device is in.
As examples:

Examples The table below shows examples of the prompts that you may see on various devices
in different modes of operation.

Terminating a The 68K Monitor will detect a loss of connection in a TELNET session and will end
68K Monitor the monitor session, allowing a new connection to be established.
TELNET Session
The 68K Monitor itself never terminates or initiates a TELNET session. Whatever
process starts the 68K Monitor handles this functionality.

Auto-Logout Since only one 68K Monitor session is allowed at a time, it automatically terminates
Timer a session if no input is received for 5 minutes (default) or after a user-programmed
interval.
Refer to: Page 4, AL - Change Auto-logout Timer for details about how this timer
can be changed.
Command Input and Response

Input to the 68K Input to the 68K Monitor is read from the ‘connected’ application / subsystem. The
Monitor input takes the form of user-entered commands.

Command Line The 68K Monitor accepts a command line:

Limitations
 that is no longer than 80 characters, and
 consists of no more than 16 separate words or symbols.
 The definition of a word or string is one or more characters separated by one
or more spaces.
 Input may be either upper or lower case, except where noted.

Command Input may be either upper- or lower-case.

Format
The format of all commands is as follows:
<command_name> < parameters arguments>

Where:
 command_name is one of the recognized commands, and
 parameter arguments are an optional list of command parameters.

Common You must format these commands in a definite way or syntax. You must understand
Command command syntax to understand detailed command descriptions in the following
Syntax chapters.

List of This tables lists some of the characters used in command syntax:
Characters
Character Name Description
/ switch identifies that the character following it affects
the type of processing performed by the
command
[] square brackets any arguments listed within them are optional
parameters that the command may use but does
not require
| OR symbol only one of several consecutive arguments listed
within parenthesis “( )” is to be used

an unrecognizable -- a general error will be issued indicating
command that the command was not recognized.

An Example, the If you type:

EDIT Command:
e [/(b | w | l | f | d)] address

According to the syntax conventions:

 The first field, e, must be entered as is, because it has no special characters
around it.
 If you press ENTER after typing just the e, the line above appears to show you
the command parameter syntax.
 The second field, [/(b | w | l | f | d)], because it is enclosed in [ ], is optional.
 Select one of the valid switches within the parenthesis ( ) or leave it blank.
 The last field, address, is required.

Entering The 68K Monitor allows editing of the command line by using regular keyboard
Commands input as well as a few special key combinations.

Regular In addition to entering any printable ASCII character onto the command line, the
Keyboard Input following characters can be used:

This key… performs this function

ESC deletes all current data on the command line and returns to the first
character position. (except D20 base and CPM)
ENTER executes any command that has been entered on the command line.
BACKSPACE removes the last character from the end of the current command
line and moves the cursor one character position to the left.

Special Control You can use these special control characters to perform advanced editing and screen
Characters navigation functions.

Command Characters Description

Abort CTRL-C returns the Monitor to the command line prompt
and aborts most commands being processed.
Note: a CTRL-C command does not work in a
TELNET connection.

Delete CTRL-D deletes the current character of the previous

command line.
Insert CTRL-I or toggles the current mode to/from overwrite or
TAB insert. The monitor always starts in overwrite
mode.
Advance CTRL-A causes the monitor to copy the character from
the previous command buffer reference location
to the current location in the input command
buffer.
This character also returns the monitor to
overwrite mode.
Repeat CTRL-R allows editing and re-execution of the previous
command by copying the previous command
line from the character at the previous command
reference location (up to the end of the previous
command buffer) into the current input
command buffer
Note: D20ME and D25 have a 5-line
command buffer.

Execute CTRL-X copies the most previously used command to

the command line and executes it.
Xoff, Xon CTRL-S the combination of CTRL-S (Xoff) and CTRL-Q
and CTRL-Q (Xon) stops and starts scrolling of the monitor’s
display.
68K Monitor Display

Output from the The 68K Monitor’s output is a stream of ASCII characters written back to the
68K Monitor ‘connected’ application / subsystem. The command executed determines the exact
contents of the output.
When encountering a system exception error, or a defined breakpoint, exception and
breakpoint handling routines will generate additional output.

Display Output While most output to the monitor port is a direct result of command input, some
occurs asynchronously of the command input.
This requires the use of two methods of output display.
 The first method uses the monitor-input process, which formats the output into
a common buffer and signals the output process that data is available.
 All output that occurs synchronously with the input uses this method,
including command data and input line display.
 The second method uses exception-handling routines to display data that may
or may not occur as the result of a monitor command, but cannot be expected to
occur synchronously with the input.
 A pSOS exchange sends this data (including unassigned exception and
breakpoint data displays) to the output process.

An Example: Once a breakpoint is set, the monitor cannot control when or if the system encounters
the breakpoint.
The exception and breakpoint display output may occur at any time, and this output
has priority over monitor input process output. This may cause occasional
interruption of a command or input in progress, or the lack of a prompt re-appearing
after displaying the data, but does not affect these functions in any way
Error Messages

Syntax Below is usage and syntax information for this command

Command Format baud baud_rate

Variables None
Parameters baud_rate = the new data rate for the port, in bps.
Example Type baud 4800 and press ENTER.
Results: The monitor switches to communicate at 4800 bps.
Special See warning below.
Considerations

About Changing The 68K Monitor has the ability to change the communication speed of the D25 and
the Baud Rate D20 ME WESMAINT ports. This is useful when downloading large files.
Example: A 1 M code file may take upwards of 40 minutes to download at
9600 bps (the default). At 38400 bps, only 10 – 15 minutes.
Note: Most PCs cannot exceed 115,200 bps, and some terminal programs
(Windows Terminal for example) may have other restrictions. Check the
respective program's User's Guide for help.

The system will not save speed changes made using this command in NVRAM.
! The monitor will return to 9600 bps after a restart.
WARNING 1 If you execute this command in a D25 monitor, it will modify the data rate of both
the WESMAINT and the D25MAINT ports, since they run off the same data rate
generator.
GE Energy Services recommends that you use this command only to speed up a
serial download, and not to redefine the operational state.

Enter the baud rate correctly, as the function is capable of setting the data rate
! to any value.
WARNING 2 Example:
Forgetting to enter the final zero when trying to change the data rate
to 19200 bps would result in a rate of 1920 bps, preventing any
further communication. A reboot will return the speed to the 9600
bps default.

enter new values for the FLASH, SRAM, and
NVRAM base address and size. Entering a
zero indicates that the item is to remain unchanged.
Once the new data has been entered, you are
prompted:
Is this data accurate? (Y/N)
Any response other than ‘y’ will cause the monitor
to
re-issue the prompts for the FLASH, SRAM, and
NVRAM base address and size.
Pressing CNTRL-C will abort the command.
If the user responds ‘y’, the command writes new
data to the NVRAM header and a new NVRAM
header CRC is calculated and stored.

Description Use this command to download configuration and application data over the serial
port into RAM or FLASH. The 68K Monitor accepts a transfer of ZMODEM
binary data to the D25 initiated either by the D25 user or by the sending terminal.
When the transfer is complete, the DOWNLOAD command returns control to 68K
Monitor’s command line.
Application code download only works when:
 executing from the BootROM, and
 the monitor has erased the FLASH region.
While the command downloads the file, it recognizes the ZLIB format of the
compressed data and uncompresses it.

Syntax Below is usage and syntax information for this command

Command Format rz [/(Vlevel | Mtimeout | Ctimeout | Wwindow)]

Variables /Vlevel verbose level, which determines the level of
debug messages displayed (default is zero, any
non-zero value will activate debug messages).
/Mtimeout set receive message timeout to the user specified
value (the default is 2000 ms).
/Ctimeout set inter-character timeout to user specified value
(default is 500 ms).
/Wwindow set receiver window size to user specified value
(default is 1400 bytes).
Special Before the start of the download, the system must suspend all
Considerations non-protected process running in the system.
 If there are parameters on the command line, the monitor
assumes that the D25 initiated the download, and allows 20
seconds for the user to activate the software that will send
data to the D25.
 If there are no parameters, the monitor assumes that the
sending software initiated the download and it will not
provide a wait period.
The command “rz” is the standard prefix used by the
ZMODEM binary protocol to start a file transfer. A terminal
using this command can connect to the D25 Monitor and
simply start sending ZMODEM data without any further user
input to the D25.

Continued on next page

RZ - ZMODEM Download, Continued

Executing this command modifies the memory of the D25, and can cause operational
! disruption.
WARNING Use caution before proceeding. Be sure that you really want to use this command
and that you use it correctly.

Note  When using ZMODEM, all files sent to the 68K Monitor must have file names.
The file name for a FLASH image must start with “PROM”. The file name for a
ZLIB compressed image must end with the extension “.ZLB”.
The name in these cases is case insensitive (i.e. “prom” and “.zlb” are acceptable as
well). The monitor assumes that any other names are non-compressed NVRAM
configuration data.
Since there is no addressing inherent in ZMODEM data, you must change the
location of NVRAM in any existing configuration before downloading if you want to
change the NVRAM header address.

Description Use this command to stop all unprotected processes, some unprotected processes, or
a specific unprotected process.
Use this command to stop all processes before CPU-intensive operations, for
example, an NVRAM download.
Protected processes must remain running at all times. Protected processes
include:
 MON monitor input process
 MOUT monitor output process
 WDOG watchdog process
 ROOT root process
 IDLE pSOS idle process
 LGIN boot login process (in some cases)
 iSCS processes, including B100 and file managers.

Syntax Below is usage and syntax information for this command

Command Format CPM / D20 / D25: sp [(pid | name)]

CCU / CCUME: sp [(pid | gpid | name)]
Variables None
Parameters (none) = suspend all unprotected processes.
pid = pSOS process ID (in hexadecimal); suspend a
specific process.
gpid = global pSOS process ID (in hexadecimal);
suspend a specific process.
name = case-sensitive process name. The monitor
supports the new process naming convention.

If you enter an entire name, a specific process

is
suspended. If you enter the first few
characters,
the command attempts pattern matching. All

matching processes are suspended.

Description Use this command to start one of these two serial port test procedures:
 an automatic loop-back test of the defined serial port
 transmits and receives a series of characters of different formats.
 manually forcing the mark or space line states from the RS-232 drivers
 allows you to monitor and adjust modem levels or frequencies.

Syntax Below is usage and syntax information for this command

Command Format CPM / D20: st /(f | l) port

CCU / CCUME / D25: st /(f | l) port [baud]
Variables /f = force mark or space states
/l = automatic loop-back test
Parameters port = serial port to test (COM#)
baud = data rate in bps (decimal)
Example Type st /l com7 9600 and press ENTER.

Results: This forces the RS-232 transmitter driver for

communications port seven (7) to perform the loop-
back test at 9600 bps.

The system displays the current state of the test.

Cancel the force test manually with CTRL-C.

The loop-back test terminates either on an error or on

completion of the test. The monitor displays the
prompt after stopping either test.
Special  These tests temporarily assume control of the specified
Considerations communications port, and disrupt any current activity.
 They may also, depending on the application, affect
subsequent operation.
To ensure that you avoid this, you must reboot the system when
you complete all testing.

ST - Serial Test, Continued

Loop Test The automatic loop-back test requires this DB-9 pin loop-back connector:
Adapter
DCD 1  ────┐
RXD 2  ──┐ │
TXD 3  ──┘ │
RTS 7  ────┤
CTS 8  ────┘

Selectable Data The command used in CCU-based and D25 products allows you to select the data
Rates rate for the loopback test.
Supported data rates in bps are:

50 110
134 200
300 600
1050 1200
2400 4800
7200 9600
38400

The command has failed when used for stress testing. Do not use the serial test for
! that purpose!
WARNING You must only use it to verify the device driver for the communication port.

Variables /g = Allows the message to be sent to a queue in a
different node
Parameters xid = pSOS exchange ID (in hexadecimal); send
message to a specific exchange.
gxid = global pSOS exchange ID (in hexadecimal); send

message to a specific exchange.

name = case-sensitive exchange name. The command
supports the new exchange naming
convention.

If you enter an entire name, the system

sends the
message to that exchange.

If you enter the first few characters, the

command attempts pattern matching. The system
sends the message to one or more
exchanges,
depending on the number of matches.
m2 - m5 = first through fourth long words in the body of the
message, in hexadecimal.
Example Type sx 304540 1 2 3 4 and press ENTER.
This sends a message identified as 304540. The command sets
the first two reserved messages to 0.

Results: The system displays the prompt unless it encounters

an error. In this case, it displays an error message
before displaying the prompt.
Special You must only use this command in a testing or debugging
Considerations context. If you send a message to an exchange
indiscriminately, you cannot predict the results.
